First report of anthracnose crown rot of strawberry caused by Colletotrichum siamense in Rajshahi district of Bangladesh.

Abstract

In March 2016, typical anthracnose crown rot (ACR) symptoms were observed on the strawberry cultivar Strawberry Festival in a farmer's field in Rajshahi District, Bangladesh. Symptoms were evident on approximately 10% of plants and included flagging of young leaves, mimicking lack of water and wilting of the entire plant in daytime heat. A lengthwise cut through the crown of diseased plants showed characteristic shades of red and white marbling. The causal pathogen was isolated and identified as Colletotrichum siamense based on morphological, molecular and pathogenicity analyses. The obtained sequences were deposited in GenBank (Accession nos.LC420017 to LC420022). This is thought to be the first report of ACR of strawberry caused by C. siamense and the members of C. siamense complex in Rajshahi District, Bangladesh.
